Sometimes, even if you like the zodiac, you just feel like your star sign doesn’t align with you. But there’s more than one form of astrology out there.

Celtic astrology, for example, was created by the Druids sometime around 1000 BC. The Celts believed that we are all derived from trees, and our date of birth can tell us something about our individual tendencies and what aspects of nature we connect with.

As such, everyone has a tree sign. Not sure what yours is? Keep reading — you may learn something about yourself.

Birch (December 24 – January 20)

Also called the achiever, birch people were born in the darkest time of year, which means they’re always striving towards the light.

This can be challenging, but it also builds character, because you’re always striving to make your life better. As such, birch people are said to be resilient, ambitious, highly driven, and natural leaders.

Rowan (January 21 – February 17)

The Rowan is known as the thinker of the Celtic zodiac, meaning that people under this tree sign are regarded as deep thinkers and visionaries. They are known for their passion and wild imagination.

However, this also means that rowan people aren’t always taken seriously because their ideas seem to come out of left field. This suits Rowan people just fine because they dislike conformity.

Ash (February 18 – March 17)

The enchanters of Celtic astrology, Ash people are artistic, imaginative and intuitive.

They see the world through the lens of art and color, which means they draw inspiration from art and spirituality. They can seem reclusive, which suits ash people just fine. They don’t need other people to understand them in order to thrive.

Alder (March 18 – April 14)

Alder people are trailblazers. As the name implies, they’re natural leaders, charismatic, charming, and passionate.

They aren’t afraid to inspire others, and as such, they tend to read as confident. Fittingly, Alder people don’t like to waste time with indecision and deliberation.

It should come as no surprise that everyone enjoys the company of this tree sign. In fact, an Alder usually has a tribe of curious, eager followers with them on every new adventure.

Willow (April 15 – May 12)

Willow people are sometimes called the observers–an appropriate title because the Druids believed that willow people were likely to be psychic.

They were thought to have a strong connection to the moon and lunar cycles, which aided in their psychic prowess, including premonitions. Beyond that, though, Willow people love learning.

If anything, their greatest downfall is themselves, because Willow people can let their fears hold them back.

Hawthorn (May 13 – June 9)

People under the Hawthorn tree sign are sometimes called illusionists.

There’s a reason for this — Hawthorn people can look very different on the outside than they do on the inside.

If you get to learn the true nature of a Hawthorn person, you should consider yourself privileged, because they only show who they really are to people they trust without question.

Oak (June 10 – July 7)

Like the oak tree itself, people born under the Oak sign are a source of strength, which is why they’re called the stabilizers.

They are strong, nurturing, generous, and wise. They firmly believe that everything will work out in the end, and make wonderful teachers and counselors. This can mean they are a bit overprotective toward their loved ones, but it always comes from a place of love and compassion.

Holly (July 8 – August 4)

The Druids called Holly people the rulers because they have a natural ability to succeed at whatever they set their minds to (and their naturally regal air).

Like the birch, Holly people are ambitious, competitive, and intelligent. They have a tendency to make even the most difficult task look simple because they are naturally gifted high-achievers.

Hazel (August 5 – September 1)

Hazel is also called the knower. Among the Celtic tree signs, Hazel people are among the most intelligent, whether that takes the form of academic intelligence or intuitive knowledge.

They have excellent memories and a natural curiosity, which can make them seem like know-it-alls. They’re also highly detail-oriented, which can make them appear obsessive at times. But it’s this same quality that makes Hazel people great organizers and thinkers.

Vine (September 2 – September 29)

The Vine is also called the equalizer, but in actuality, Vine people are often viewed as having fluid personalities to match the changing of the seasons.

This can mean that Vine people are indecisive, as well as contradictory to themselves and others. But this fluidity comes with the benefit of seeing both sides of the story (thus the title of the equalizer).

This also means Vine people are very empathetic, despite their tendency toward mood swings and their taste for finer things.

Ivy (September 30 – October 27)

Ivy people are called survivors because life will often throw them many trials and tribulations.

However, this means that Ivy people are also among the most loyal and compassionate, and are known as the wounded healer in the Celtic zodiac, always prepared to help someone in need.

Reed (October 28 – November 24)

Reed people, also called inquisitors, are born at the time of the Celtic new year, Samhain (pronounced sow-en).

True to the title, people in this tree sign are truth seekers and truth keepers–they love digging for the hidden cause of things. This means they can easily be drawn to scandal and gossip, but they’re also great journalists and historians.

They’re also people lovers because they can’t resist another mystery to uncover.

Elder (November 25 – December 23)

Elder people are appropriately called seekers (as in thrill seekers).

They’re born at a time when the light is fading, and they live life the same way: in the fast lane, with a passion that makes them appear reckless. However, Elder people are actually deeply thoughtful and philosophical, as well as extremely honest.

In fact, they tend to assume they’re right, and always have faith that they’ll bounce back quickly.
